No way. In fact our helpdesk isn't even full admins, they have to use a special account for that.
Only the network admins have such rights.
our developers have the rights they need to specific servers and places.
It's simply too risky............. accidents happen, plus most "risks" run with the privilages of the local user.............giving them full admin rights allows them to circumvent security, lock registry entries to prevent things from running - or allowing things to run, installing software and hardware not allowed, etc.
